Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Surface tension
Administrative data
Link to relevant study record(s)
- Endpoint:
- surface tension
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because based on structure, surface activity is not expected or cannot be predicted
- the study does not need to be conducted because surface activity is not a desired property of the material
- Endpoint:
- surface tension
- Type of information:
- experimental study
- Adequacy of study:
- supporting study
- Study period:
- 2009
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 115 (Surface Tension of Aqueous Solutions)
- Deviations:
- no
- GLP compliance:
- no
- Type of method:
- ring method
- Surface tension:
- 73 mN/m
- Temp.:
- 20 °C
- Conc.:
- 169 g/L
- Conclusions:
- The surface tension of a 169.0 g/L solition of tin sulfate was determined to be 73 mN/m at 20.0°C
- Executive summary:
The surface tension of a solution of the test item in water was determined according to OECD 115 in a non-GLP study. The surface tension of a 169.0 g/L solition of tin sulfate was determined to be 73 mN/m at 20.0 °C. This is equal to the typical surface tension of water at 20 °C.

Description of key information
In general the study does not need to be conducted, because surface activity is no desired propertiy of the material and in addition surface active properties can not be predicted based on the structure of the test item.
This is confirmed by a supporting study:
The surface tension of a solution of the test item in water was determined according to OECD 115 in a non-GLP study. The surface tension of a 169.0 g/L solition of tin sulfate was determined to be 73 mN/m at 20.0 °C. This is equal to the typical surface tension of water at 20 °C.
Key value for chemical safety assessment
- Surface tension:
- 73
- in mN/m at 20°C and concentration in mg/L:
- 169
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
